Former national security advisor Michael Flynn revealed some of his sources of income that he had previously omitted during his public financial filing, according to an Associated Pressreport.

A person close to Flynn confirmed that Flynn was forced to amend his financial disclosure after he “forgot” to include income from the Trump transition and a data analysis company that helped the 2016 campaign. The firm, SCL Group, has come under fire in recent months when it was discovered that CEO Alexander Nix was using “dirty tricks” for both Trump and the Brexit vote.

Flynn’s amended report revealed about $28,000 from the Trump transition and more than $5,000 consulting for a plan to build nuclear power plants all over the Middle East. While he has disclosed in the past that he worked for the clients, he never reported receiving money from them.

Flynn “played an advisory role to NJK Holding relative to its investment interests in security,” NJK said in a statement to the AP. The statement claimed that he “provided his counsel and guidance on public sector business opportunities for secure communications technology within the U.S. Department of Defense” as well as other agencies.
